You expect smooth, effortless steering when you drive your 2012 Ford Fusion. But over time, low or degraded power steering fluid can make steering feel stiff, noisy, or uneven. In this guide, you’ll learn how to check the fluid level, assess its condition, and maintain your system—step by step.
Why Checking Power Steering Fluid Matters
Monitoring your power steering fluid is a straightforward yet crucial routine. Here’s why it matters:
- Smoother Steering: Adequate fluid ensures easy turning and precise control.
- Protects the Pump: Proper lubrication avoids premature wear and expensive pump repairs.
- Detects Leaks Early: A slow drip can lead to big trouble if left alone.
- Cost Savings: A regular check helps avoid costly repairs down the road.
What You’ll Need
- Clean shop towel or microfiber cloth
- Paper towels for any spills
- Optional: Latex or nitrile gloves
- Funnel (optional but helps prevent spills)
No specialized tools are needed—you’ve got everything you need to get started!
Step 1: Safety First
Before you do anything:
- Park on a level surface and firmly engage the parking brake.
- Turn off the engine and let it sit for 5–10 minutes to cool down.
- Open the hood and secure it with the prop rod.
A level surface and cooled engine ensure accurate readings and safer handling.
Step 2: Locate the Power Steering Reservoir
In the 2012 Fusion (available in 2.5L I4, 3.0L V6, and later 1.5L EcoBoost), the power steering reservoir is:
- Translucent white plastic with a black cap labeled “Power Steering.”
- Mounted near the front passenger side of the engine bay—closer to the firewall in the EcoBoost but still easy to spot.
- Connected to a hose leading to the power steering pump.
Look for a small, rounded-shaped tank that stands out near the serpentine belt area.
Step 3: Clean the Reservoir Area
Wipe the reservoir cap and surrounding area to prevent debris from getting in. Contamination could harm the pump or rack-and-pinion system.
Step 4: Check the Fluid Level
The reservoir includes a dipstick inside the cap. Here’s how to use it:
- Unscrew or pop off the cap (avoid tipping the reservoir).
- Wipe the dipstick clean with a towel or paper towel.
- Reinsert the cap fully, then remove it again to check the level.
- Compare the fluid level to the embossed marks:
Dipstick Marking | Meaning |
---|---|
LOW/HOT | Low—needs a top-up |
FULL/HOT | Optimal level |
If the fluid is between LOW and FULL, you’re fine. If it’s below LOW, you should add fluid; if it’s above FULL, remove the excess.
Step 5: Assess Fluid Condition
Don’t just check the level—make sure the fluid is in good shape:
- Healthy fluid: Clear to light pink/red with a mild oily scent.
- Signs of trouble: Dark brown/red, black particles, burnt smell.
If it looks or smells bad, you should schedule a fluid flush soon.
Step 6: Top Up or Remove Excess Fluid
Topping Up
If the level is low:
- Use Ford MERCON LV power steering fluid or an exact equivalent.
- Insert a funnel, pour slowly, and re-check after each small addition.
- Fill to just below the FULL/HOT line—never overfill.
Removing Excess Fluid
If overfilled:
- Use a turkey baster or fluid syringe to carefully remove extra fluid.
- Never loosen hoses—this can introduce air or cause leaks.
Step 7: Circulate Fluid
After adding fluid:
- Start the engine and let it idle.
- Turn the steering wheel fully left and right at least 3–5 times.
- Turn off the engine and wait a few minutes.
- Recheck fluid level—add more if it dropped.
This ensures the fluid reaches all parts of the system and releases trapped air.
Step 8: Final Cleanup & Follow-Up
- Wipe any spills with paper towels and dispose properly.
- Secure the reservoir cap tightly.
- Close the hood fully.
Watch the fluid level over the next week. If it drops again, inspect for leaks under the car or around hoses and the pump.
When Should You Flush the Fluid?
Consider a full power steering fluid flush if you notice:
- Dark, contaminated fluid
- Whining pump or stiff steering
- Leaking fluid under the engine bay
- Factory recommended interval: Every 50,000–75,000 miles
A flush removes old fluid, debris, and air—all vital for healthy steering performance.
Common Troubleshooting Questions
How often should I check the fluid?
Check once a month or before long trips to catch low levels early and prevent damage.
Can I use automatic transmission fluid instead?
No—Transmission fluids have different formulas and may harm seals or decrease performance. Always use MERCON LV or exact manufacturer-approved fluid.
I keep topping up—now what?
If levels drop again shortly after topping up, you likely have a leak. Inspect hoses, reservoir, pump, and rack for signs of fluid; replace or tighten as needed.
Is driving safe with low fluid?
Driving with low fluid makes steering heavy, noisy, and unreliable—especially in emergencies. Fill it before hitting the road.
Real-World Case: John’s Resolute Fix
John owns a 2012 Fusion 2.5L with 120,000 miles. He noticed whining noise and difficulty turning. He checked the reservoir and saw dark, murky fluid and a low level. He topped up and flushed the system at a local shop. Post-flush, steering was smooth and quiet. He now checks fluid monthly and hasn’t had any issues since.
Maintenance Schedule
Task | Interval | Purpose |
---|---|---|
Fluid Level Check | Monthly | Ensures adequate fluid and early detection of leaks |
Top-Up As Needed | When below LOW | Prevents pump strain and steering issues |
Fluid Flush | Every 50–75k miles | Removes old fluid and contaminants |
Pro Tips & Best Practices
- Dedicated funnel: Keeps fluid clean and avoids contamination.
- Microfiber towels: Prevent scratches and absorb spills.
- Check belt tension: A worn serpentine belt can reduce pump efficiency.
- Keep a log: Note dates, fluid levels, and any observations for future reference.
Troubleshooting Quick Guide
Issue | Likely Cause | Quick Fix |
---|---|---|
Stiff steering | Low fluid | Top up to FULL/HOT |
Whining pump | Air or old fluid | Steering wheel turns + fluid flush |
Fluid leak | Bad hose/seal | Inspect and repair component |
Dark fluid | Contaminated fluid | Flush and replace fluid |
When to Call a Mechanic
DIY checks cover the basics, but get professional help if:
- There’s a major fluid leak underneath.
- Fluid level keeps dropping after topping up.
- You’re uncertain about fluid types or flush procedures.
- Steering issues persist after maintenance.
These symptoms may point to a worn pump, failing rack, or damaged hose that need specialist attention.
Conclusion
Checking the power steering fluid in your 2012 Ford Fusion is a quick, simple task with big benefits. Regular checks keep your steering smooth, protect your system, and help catch problems early—saving you time and money.
Start checking monthly, top up with the right fluid, and plan a full flush around 50,000–75,000 miles. Make this part of your routine and enjoy confident driving all day, every day.
